is krishnamurthy iit acadamy one of the best iit coaching centre for iit

Hi Nikhil

It depends on your need as well, the distance of your home to your coaching. Before joining I will suggest please have a google search on spanedea and get a trial class there. And then enroll to any coaching,

Coaching will depend on the type of teachers you have there, the way they teach you and how you can grasp it. As far as material and test series are considered all are equal. You can also check askiitian throughly as its a good interface.

It will also depends on the board from which you are appearing for your 12th exam.

I think the best coaching institute on the basis of number of students who go to IITs from that particular coaching is FIITJEE . 

But there are many good centres like this particular askIITians . !

ITS GUD BUT NOT THE BEST
